Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Information processing terminals struggle to connect electronic devices to a wireless network when they are out of the communication range of the access point, leading to setup failures and user confusion.
Innovation Solution
The information processing terminal obtains connection information for multiple access points, stores it, and selects the appropriate connection information based on its current position, then transmits this information to an electronic device using a method with a narrower communication range, such as NFC, to facilitate setup.

1Length of moving object
If the information processing terminal transmits connection information to an electronic device using a wide communication range method, then the transmission can be performed over long distances, but the electronic device may be out of the communication range of the access point corresponding to the connection information, causing setup failure
Solution Approach 1:
The patent introduces an intermediary process where the information processing terminal first connects to the electronic device via a narrow communication range method (NFC) to establish proximity confirmation. This intermediary step ensures that the electronic device is physically close to the terminal before transmitting Wi-Fi connection information, thereby guaranteeing that the device is within the access point's communication range and preventing setup failures.
Solution Approach 2:
The patent applies preliminary action by performing the narrow communication range connection (NFC) before transmitting the wide communication range connection information (Wi-Fi). This preliminary proximity confirmation ensures that the electronic device is within the correct communication range of the access point before the actual network setup begins, preventing failed setups due to being out of range.
2Reliability
If the information processing terminal uses a narrow communication range method to transmit connection information, then the electronic device is ensured to be within the access point's communication range, but the transmission distance is limited
Solution Approach 1:
The patent segments the connection establishment process into two distinct phases: first using a narrow communication range method (NFC) for proximity confirmation and device pairing, then using a wide communication range method (Wi-Fi) for transmitting connection information. This segmentation allows each communication method to be used for its optimal purpose, combining reliability with extended functionality.
Solution Approach 2:
The patent dynamically switches between different communication methods based on the requirements of each step. The narrow communication range method is used initially for proximity verification, then the system transitions to the wide communication range method for actual network connection setup. This dynamic approach optimizes both reliability and communication range throughout the process.
3Ease of operation
If the information processing terminal automatically transmits connection information without verifying proximity, then the setup process is simplified, but the electronic device may be out of the access point's communication range, causing user confusion
Solution Approach 1:
The patent implements self-service by enabling the information processing terminal to automatically verify proximity through NFC connection and automatically select appropriate connection information for transmission. This self-verification process occurs without user intervention, maintaining ease of operation while ensuring reliability by confirming the electronic device is within the correct communication range before proceeding with the setup.
